Question

why we can not stand one place at long time

Answer 1

We cannot stand at one spot for a long time as the mindset tells us to do something or the other every time. For me, its impossible to do that for even half an hour or so!

Answer 2

Hey mate your answer is ...........

The fields from the Earth-gravity plus centrifugal plus Coriolis and other forces are almost exactly constant in time. So the human may either be able to deal with constant forces or not. If there are swings, the cause is clearly inside the human. Small changes of the tension in the muscles-due to small electric signals or variations of the concentration of sugars etc. have observable impacts on the location of the bones etc. A way to answer is that the human muscles are surely much more volatile than the Earths gravity+centrifugal fields.
